According to Mutto, the incident began with the gunman trying to merge in front of his truck. Mutto says the other driver did not make it in time and a few miles down the road the man was waiting on the side of the road for him to pass.

He says that's when the shooting started.

"I started weaving and bobbing because I didn't want to get shot in the head again," Mutto said.

Police are searching for the suspected gunman last seen in a silver BMW or Lexus sedan.
